ROY S. BURT, OF FREEPORT, ILLINOIS.

SCBUBBING-MACHINE.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application flied January 3, 1916. Serial No 69,841.

To all whom it may concern:

lie it known that I, ROY S. BURT, a citizen of the United States,residing at Freeport in the county of Ste )henson and State 0 Illinois,have invented certain new and useful Improvements in Scrubbing-Machines,of which the following is a specification.

My invention relates to improvements in apparatus for washing,scrubbing, or cleaning articles of apparel, such as gloves, laces,collars, cuffs, embroidery, muillers or the like, while not necessarilyrestricted to such use.

An important object of the invention is to provide apparatus of theabove mentioned character, which may be operated expeditiously to cleanarticles of the above mentioned character in a thoroughly satisfactorymanner.

()ther objects and advantages of the mvention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure 1 is a side elevation, partly in section, of apparatusembodying my invention, Fig. 2 is a horizontal sectional view taken online 2-2 of Fig. 1, Fig. 3 is a plan view of the same, and, Fig. 4 IS anenlarged detail elevation of a holding element or ring for certain ofthe brushes.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 designates a base.upon which are mounted vertirul stamlards 6, having bearings 7, securedto their upper ends. Journaled in these hearings are stub shafts 8. ()ncstub shaft may be driven by a pulley 9, receiving rotation from a. belt,not shown, while the other stub shaft may be manually rotated by meansof a handle or crank 10, rigidly secured thereto. Arranged between thestub shafts 8 is a bodily rotatable receptacle 11, illustrated as abarrel, while the invention is in no sense restricted to this form ofreceptacle. The stub shafts 8 carry flanges 12 bolted or otherwiserigidly secured to the barrel 11, as shown at 13.

The barrel 11 has its bottom 14 provided adjacent its periphery with anannular group of openings or recesses 15, receiving the lower ends ofrods or wires L6 of wire twisted fiber brushes 17. These brushes arepreferably cylindrical and are made by twisting two or more strands ofwire about the fiber or bristles. At the upper ends of the brushes therods or wires 16 extend upwardly beyond the brush portion and areadapted to fit within recesses or notches formed in a retaining ring 18.This retaining ring is mounted in the top of the barrel and has a flange19 rigidly secured to the barrel by screws or bolts 20 or the like. Itis thus apparent that the openings 15 and ring 18 serve as means forholding the wires or rods 16 against displacement, but will permit oftheir removal when desired. The wires or rods 16 are suitably resilientso that the brushes 17 may be removed. These brushes may rotate slightlyupon their axes, the major portions of the brushes 17 are or may bespaced from the inner surface of the barrel, forming a water chamber orspace therebetween.

Arranged upon the bottom 14 of the barrel or receptacle is a fiat coiledbrush 21, having a twisted body portion or carrier 22 which is attachedor anchored to the bottom by means of staples or screws 23. The top ofthe barrel is normally closed by a removable cover 24, fitting within aninterior inner groove 25, as shown. Secured to the inner side of thecover 24 is a flat coiled brush 26, substantially identical with thebrush 21.

Means are provided to detachably hold the cover 24 in the closedposition comprising approximately U-sbaped arms 27, pivotal y connectedwith cars 28 secured to the top of the barrel 11, as shown. WVhen theseU-shaped brackets are swung outwardly they are disposed out of the pathof travel of the cover 24 and the cover can be removed. When they areswung inwardly, they are adapted to be arranged between the ends of arotatable latch 29, pivoted to the cover, as shown at 30.

The numeral 31 designates a flat coiled brush, loosely disposed withinthe barrel 11 and adapted to move freely therein during the rotation ofthe barrel. I

In use, the articles of apparel to be cleaned are loosely thrown intothe barrel 11 together with the movable brush 31, in the presence of asuitable cleaning liquid. such as a solution of water and soap. Thebarrel is rotated either mechanically or manually and the articles ofapparel to be cleaned are thrown into contact with the va- Hill ll l

rious brushes secured to the barrel and also in contact with the movablebrush.- It has been found that this operation will thoroughly clean thearticles of apparel in a highly ex )editious manner.

It is to L0 understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described the invention, I claim:

1. In apparatus of the character described, a. movable receptacle,brushes extending longitudinally within the receptacle and substantiallycovering the interior of the side of the receptacle, means for pivotallyconnecting the opposite ends of the brushes with the ends of thereceptacle, so that the brushes may turn upon their longitudinal axisand a cover for the receptacle.

2. In apparatus of the character described, a movable receptacle,cylindrical brushes extendin longitudinally within the receptacle andsidistantially covering the interior of the side of the receptacle,means for pivotally connecting the opposite ends of the brushes with theends of the receptacle, so that the brushes may turn upon theirlongitudinal axis, substantially cylindrical coiled brushes secured tothe top and bottom of the receptacle to provide a continuous brushingsurface, and means to move the receptacle.

3. In apparatus of the character described, a support, a receptaclepivoted upon the support and adapted to be turned upon its transverseaxis, said receptacle increas ing in diameter toward its centralportion, brushes extcmling longitudinally within thc receptacle in closerelation and having their central portions spaced a substantial distancefrom the sides of the receptacle to provide a passage between thebrushes and such sides, means pivotally and detachably connecting; theends of the brushes with the ends of the rccc )tarle so that the brushesmay turn upon their longitudinal axis and he removed when desired, andmeans to rotatc the receptacle.

In testimony whereof I. ullix my signature in presence of two witnesses.
